Ann: Website on dark-haloed crater and dark mantle finding aids

This is to announce a website concerning finding charts and an updated
observing list for dark haloed craters, dark mantled regions, and
cryptomaria on the nearside face of the Moon for the amateur lunar
observer. 57 figures are used to illustrate features and their
positions. The 1976 ALPO Dark Halo Crater Catalogue (N=83) has been
expanded to 194 entries.
